there is the mess which is who owns Amiga and its IP.
But the lawsuit is not on the 'Amiga' name but rather on the OS source code (who owns the code). Personally (and this is just a personal opinion) I can't understand why Amiga Inc. is trying to stick with amiga workbench or any derivation of it. Linux/BSD/Windows have all the market. So why not they concentrate on building an apple like computer, brand is 'Amiga' and install some modified version of BSD!! This would also solve the 'there is no software for amiga' problem.
I know I over simplify thing ... but can't really understand the business strategy of Amiga Inc.
